- Name the three major assumptions made by the "Cell theory". (i) The lipid membrane is composed of lipid molecules. Explain the principle of membrane formation highlighting the role of the physical properties of the lipids. (ii) Comparing dimensions and length scales is often a first step in an analysis. Give an approximate value for the thickness of a lipid bilayer and the linear length of a helical turn of a DNA double helix. A technician wants to amplify DNA from a patient sample. However, the lab is not equipped with a thermocycler. (i) (ii) Name two methods for DNA amplification that can be operated at constant temperature and give their acronyms. Explain these two methods in detail using a schematic and name all necessary components that are required to perform the amplification. Describe the main function of the middle ear.

Explain your answer. b) One difference between bacterial and eukaryotic membranes is the presenceof cholesterol in eukaryotic membranes. What is the structure of cholesterol?Explain how adding cholesterol to a phospholipid membrane will affect thestability of the membrane. c) “Anammox” bacteria are unique in that they can perform anaerobic ammoniaoxidation, or the production of nitrogen gas from ammonia (Damasté et al. Nature2002, 419, 708.). Intermediates along this reaction pathway include hydrazine(N2H4) and hydroxylamine (NH2OH), both of which are extremely toxic to the cell.The ammonia oxidation reactions are believed to occur inside a membrane-bound structure within the cell called the “anammoxosome.” The structure of oneof the lipids of the anammoxosome is shown…arrow_forward

When phospholipids are added to an aqueous environment (consisting mostly of water) the phospholipid molecules will spontaneously assemble into a phospholipid bilayer where the layers are held together by weak attractive forces between molecules. These structures are often seen in nature as cell and organelle membranes. 12. Consider animal cells, which are only bound by a cell membrane and plant cells which are bound by both a cell membrane and a cell wall. Are cell membranes flexible (fluid)? Provide specific examples to support your answer. 13. Explain why a phospholipid bilayer is flexible. terms of the strength of the forces that hold it together. 14. Refer to Model 1. a. What happens to the shape of the hydrophobic tail in a phospholipid when a double bond is present in the carbon chain? b. Explain why the flexibility (fluidity) of a membrane increases when more of the phospholipids in the layers contain double bonds. 15.

Which of the following is one of the ways that will keep the membranes of such vegetables to remain fluid when it is extremely cold? A) by increasing the percentage of unsaturated phospholipids in the membrane B) by decreasing the number of hydrophobic proteins in the membrane C) by increasing the percentage of cholesterol molecules in the membrane D) by co-transport of glucose and hydrogen 2. After a membrane freezes and then defrost, it often turns out to be loose to solutes. The best logical reason for this is that: A) the lipid bilayer loses its fluidity when it freezes.
